In a renewable energy-based system, energy storage must match the energy demand with supply. Usually a lead-acid battery is utilised as a short-term energy buffer. A system, which has a combination of an electrolyser and a high-pressure hydrogen tank for long-term energy storage, is considered in this paper. The cost intensive components are sized considering the least cost and by performing a life cycle costing of the system. The optimum battery capacity obtained is 19 kWh, which is equivalent to 2.2 days of autonomy. At present, energy storage cost in the long-term storage is found 2.16 per kWh whereas the cost goes down to 0.92 per kWh when the target cost of the fuel cell and the electrolyser is considered. Around 15–20% of the demand is supplied by the long-term storage.

In an environment of limited and decreasing budgets in the private and public sectors, it is increasingly important that investments made in pavement infrastructure are maximized to their fullest potential. Pavement interlayers, also known as geosynthetics, can be integrated into asphalt mix overlay applications to limit the intrusion of water and reduce the reflective cracking, thereby promoting long-term pavement performance.
Although there is no single solution that can prevent reflective cracking, pavements...

AbstractWater authorities around the world are faced with the problem of ageing distribution networks and often only limited historical data on which to base a sound long term, cost efficient replacement policy. The LICAN approach to whole of life costing is introduced and a hypothetical case study is used to demonstrate the importance of such an approach. A selection of pipe networks utilizing different pipe materials (PVC, DI and PE) are modeled to determine their whole of life cost, taking into account installat...

It was prepared in response to a need to find a robust method of cost analysis for improved access, both to safe drinking water and to adequate sanitation. The manual and software provide criteria and procedures that ensure the achievement of maximum community health benefits at the minimum cost of investing in improved water supply and sanitation technologies.To facilitate the application of costing methods to actual projects, a basic tool was developed using Microsoft Excel, which is called a water supply...

This paper provides a framework for life cycle cost analysis of products at the design stage based on reliability and maintainability parameters. When dealing with reliability field data, proper selection of models for time-to-failure data is essential as it affects the expected number of failures. The conventional time-to-failure analysis techniques rely on the major assumption of independent and identically distributed time between failures which is, in fact, not appropriate for all systems. This can lead to...

The civil construction industry has been an industry that significantly impacts the environment due to the amount of materials used in the construction process. Considering this fact, one must consider how to control and manage the environmental, social and economic impacts that permeate their life cycle, which is, according to the literature, between 40 and 100 years. The relevance of this issue, with regard to environmental, social and economic impacts in the civil construction industry, can be found in the...
